FrankenTurbo F660 Twin-Scroll Hybrid Turbocharger - BMW F3X 440i/ix

Product Details

The F660 Hybrid Turbocharger is a precision-engineered forced induction unit designed for the B58B30M0 engine. This upgrade addresses the volumetric efficiency limitations of the Gen 1 B58 platform by increasing the flow capacity of both the intake and exhaust sections of the turbocharger. Through CNC-machining of the internal volutes and the use of a specialized mixed-flow turbine design, the F660 significantly reduces backpressure (PMEP). This results in lower Exhaust Gas Temperatures (EGTs) and allows for more aggressive ignition timing, providing a safer and more reliable power increase for tuned 4-series applications.

Key Features

• VSR High-Speed Balancing: Every rotating assembly is balanced on a Vibration Sorting Rig (VSR) at speeds exceeding 115,000 RPM to ensure longevity.

• CNC-Ported Manifold: The integrated manifold is internally matched to the enlarged turbine wheel to optimize gas velocity and minimize turbulence.

• Inconel 718 Construction: The turbine wheel is cast from high-nickel Inconel 718 for exceptional resistance to heat and blade deformation.

• Modular Bolt-On Design: 100% "plug-and-play" fitment with standard intake inlets, downpipes, and charge pipes.

• Tuning Versatility: Fully compatible with all major B58 tuning suites.
